Joel’s Mercedes-Benz S600 spun out of control Saturday at about 10:30 p.m. as it rounded a dangerous bend in Sag Harbor and sideswiped a tree, cops and residents said.

One source told The Post after the crash that Joel was sober at the time, and another source said that because there was no smell of alcohol on the musician or in the car, cops did not give him a breath test for alcohol.

Joel was taken to University Hospital at Stony Brook after the crash and a blood test showed he had not been drinking, a source said. He was released from the hospital Sunday morning.
